![]() That padding is offset in rows for the first and last column via negative margin on. Columns create gutters (gaps between column content) via padding.Less mixins can also be used for more semantic layouts. col-xs-4 are available for quickly making grid layouts. Content should be placed within columns, and only columns may be immediate children of rows.Use rows to create horizontal groups of columns.container-fluid (full-width) for proper alignment and padding. Here's how the Bootstrap grid system works: Grid systems are used for creating page layouts through a series of rows and columns that house your content. It includes predefined classes for easy layout options, as well as powerful mixins for generating more semantic layouts. For more details, see this later post.Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. There are far more pattern designs possible with CSS3 gradients than I originally thought. Cheers! :) Added afterwards: Other patterns It will be very easily possible if conical gradients start being supported (currently they’re not even in the spec yet).Ĭan you think of any other popular patterns that can be created with CSS3 and no images? If so, let me know with a comment. I still haven’t managed to think of a way to create a regular checkerboard (not at 45°) without needing an unacceptably large number of gradients. It consists of two 45° linear gradients and two -45° linear gradients, each containing ¼ of the dark squares. ![]() The hardest one to figure out was the checkered pattern. To create the picnic-style pattern, you just overlay horizontal stripes on vertical stripes. To control the size of each tile, you can use background-size: However, without anything else, the tile will occupy the whole container. background-color serves two purposes here: Setting the color of half the stripes and serving as a fallback for browsers that don’t support gradients. Why transparent instead of the actual colors we want? For flexibility. For example the gradient for the horizontal stripes is:īackground-image: -webkit-gradient(linear, 0 0, 0 100%, color-stop(.5, rgba(255, 255, 255. I guess this makes it obvious how to create the tile for the stripes (unless you’ve never created a striped background before, but teaching you this is beyond the scope of this post). In effect, the color suddenly changes at that position rather than smoothly transitioning. ![]() If multiple color-stops have the same position, they produce an infinitesimal transition from the one specified first in the rule to the one specified last. The main idea behind the technique is the following, taken from the CSS3 Images spec: View demo (Works in Webkit, Firefox 3.6+, Opera 11.50+ and IE10+) What you might not be aware of, is that CSS3 gradients can be used to create many kinds of commonly needed patterns, including checkered patterns, stripes and more. I assume you know how to add multiple color stops, make your gradients angled or create radial gradients. You’re probably familiar with CSS3 gradients by now, including the closer to the standard Mozilla syntax and the ugly verbose Webkit one. 22 December 2010 2 min read 0 comments Report broken page
